Occurs in headwaters and also in the lower reaches of rivers. Its food depends on the biotope in which it is found, but it feeds mainly on arthropods. It prefers larvae of aquatic insects like Trichoptera, Chironomidae & Ephemeroptera and ants, which are found on the river vegetation or those which fall into the water (Ref. 12225). Maximum length reported to reach 4 cm TL (Ref. 2059).
出现于河川源头以及在河的下面范围方面。 它的食物仰赖生存环境在它被发现, 但是它主要捕食节肢动物。 它偏爱像毛翅目的水生昆虫幼生, 摇蚊 & 蜉蝣与蚂蚁, 那是发现于河植物或者那些那一个掉入水中.(参考文献 12225) 最大的长度报告达到 4 公分TL 。 (参考文献 2059)
